{COOLING SYSTME FOR ENGINE ROOM}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine room cooling system, and more particularly, to an engine room cooling system capable of lowering the temperature of an engine room with a simple configuration.

The car is structurally divided into a car body and a chassis.

The vehicle body is a part including an engine room and forms an outer shape of the vehicle. The engine room is usually provided with an engine, a transmission, a cooling device, various types of fans, and the like.

Since such an engine room is a space in which an engine with a high temperature is heated during driving, optimization of heat flow for the engine room layout at the vehicle development stage must be considered as essential for effective cooling and prevention of engine deterioration.

Therefore, each automobile manufacturer has made efforts to improve the cooling performance through various studies such as analysis of the influence of the heat flux on the layout in the engine room.

That is, the improvement of the elements affecting the heat flow in the engine room, namely, the span distance of the left and right side members and the lateral distance of the strut housing, the simplification and the optimum arrangement of the components and the flow structure in the engine room, the cooling fan tilting, By optimizing the structure, we are optimizing the heat flow, and by doing so, we are getting some level of improvement such as cooling and heat prevention.

However, thermal flow optimization for the engine room layout alone can provide partial performance improvements, such as engine cooling and heat dissipation prevention, but it is not possible to improve the overall engineering performance aspect of the engine room: fuel economy or emissions, acoustics, aerodynamics, etc., have not achieved sufficient improvement.

In addition, in the related art, the cooling module has been designed to optimize the structure and arrangement of the cooling fan (such as cooling fan tilting), active air flap application, air guide arrangement, It is a fact that the improvement effect and range is limited in the overall aspect of the room and there is a limit to distributing the heat flow to the proper place due to the complicated engine room flow characteristic.

Further, in relation to noise reduction in a normal vehicle, an engine cover for covering the upper portion of the engine and an under cover for installing the engine room are mounted in the engine room. However, in view of noise reduction, Improvement and optimization of materials, and improvement of materials. However, there is no proper consideration for fuel economy or aerodynamics.

In order to optimize the engine room heat flow from a cooling point of view, a more advanced engine room heat management optimization structure is needed.

The encapsulated intake duct may be arranged in the vehicle front direction with respect to the encapsulated exhaust duct.

The engine is a single intake system I-type engine, and the main duct, the encapsulated intake duct, and the encapsulated exhaust duct may be disposed on one side of the engine.

Wherein the main duct, the encapsulated intake duct, and the encapsulated exhaust duct are disposed on one side of the engine, and in the opposite direction, the main duct and the main duct are branched from the main duct, And a capsule encapsulation exhaust duct formed in the direction of the exhaust manifold inside the encapsulation.
